Through theoretical analysis and experimental study, the authors believe that sweep speed and laser power are two critical factors influencing quality of prototype shaping in laminated object manufacturing(LOM). Starting from principle of conservation of energy, a proportional model of sweep speed and laser power is set up by combining with the specific demand of LOM prototype manufacturing technology. Good match of them can be realized by adopting control system of tracking and coupling type;and quality of shaping of LOM prototype can be determined.A discussion on the usability of control system of tracking and coupling type is made simultaneously.It is not only suitable for the manufacturing technology of LOM prototype but also suitable for multiple technologies of rapid prototyping manufacturing such as FDM, SLS, SLA, etc.
